The BU4240F is a CMOS Voltage Detector IC from ROHM Semiconductor, designed for high accuracy and low current consumption. It features an adjustable output delay time that can be set using an external capacitor, making it suitable for various applications requiring precise timing. The device operates within a detection voltage range of 0.9V to 4.8V in 0.1V increments, with a typical accuracy of ¬±1.0%. The BU4240F consumes a low current of approximately 0.55¬µA and operates effectively across a wide temperature range of -40¬8C to +125¬8C. It is available in compact packages, including SSOP5, SOP4, and VSOF5, which are compatible with standard footprints. This product is particularly useful in circuits involving microcontrollers or logic circuits that necessitate a reset function.
ROHM's low voltage CMOS reset ICs utilize CMOS processes for high precision and low current consumption. In addition, a delay circuit is built in, enabling arbitrary setting of the delay time via external capacitor. The extensive lineup includes both Nch Open Drain and CMOS output types in a wide range of detection voltages (from 0.9V to 4.8V, in 0.1V steps), enabling selection of the ideal solution based on customer requirements. Tthe entire series is of course both lead-free and RoHS-compliant.
